Someone can check me on this but I THINK it posts a local copy of the image instead of “hot linking” to the picture. (Which, in a rare case, “hot linking” could cause a problem if the source site changes the image but keeps the same link.)

Also, if you came from the original forum, pm me or post in the Welcome Surprise thread and I can up your trust level which will allow you more than 15 posts per day.
You may also pm me at the other forum if you need additional assistance.
